DIAMOND CUT

Cut refers to diamonds’ proportion. The beauty of a diamonds really depends on how proportional it’s cut, as it will affect how the diamonds reflect and diffuse the light that enters it.

A proportional diamonds cut will reflect the light towards to where it came, so the diamonds will appear sparkling and shinny. The following are three light patterns reflected by a diamonds:

SHALLOW

If a diamonds faceted and cut too shallow, the light will enter the pavilion at low angle and it will passes the facet, escaping through the bottom of the diamonds.

DEEP

Too deep diamonds cut will let the light enters the first pavilion. It will be reflected to the second pavilion, but in a lows angle, so the light won’t reflected back toward the crown but it will escape to the bottom of the diamonds.

IDEAL

A proportional diamonds cut will let light enters the pavilion at proper angle. It will reflect back toward the diamonds crown.

PEAR CUT

PRINCESS CUT

EMERALD CUT

ASSCHER CUT

CHUSSION CUT

RADIANT CUT

*Round shaped diamonds is the most popular choice. It usually has a higher grade more than any other shapes, since it is able to reflect the light perfectly and maximize the diamond sparkles.

DIAMOND CARAT

A diamond’s price is determined by its carat weight. Carat is diamonds’ unit weight; it does not refer to a diamond’s size. A carat is equal to 200 milligram. The bigger carat weight is, the higher its value and price. There’s still a really few number of diamonds with big carat produced. For example, one diamonds with 2 carats weight is more expensive than two diamonds with 1 carat for each, even if the cut, color and clarity grades are the same.

What is CT.TW ?

Carat (CT) is used to describe a diamonds weight, but a CT.TW is used to describe total carat weight of numbers of diamonds studded as jewelry. For example, if a ring has three diamonds with 0,10 carat each, then the total carat weight are 0,30 CT.TW.

CERTIFICATE DIAMOND

Before purchasing diamonds, make sure the diamonds has a certificate as a proof that the diamonds has been evaluated, measured and observed by experts with a magnification glass, microscope and another proper equipment. Diamond’s certificate, or commonly called diamond’s grading report, contains scientific data about diamonds dimension, clarity, color, symmetric, and other characteristics formulated by gemologist. Mostly, diamonds will be provided with a certificate if the weight starts from 0,30 ct.

There are now many laboratories that provide such certification, one who is known to have a high consistency and accuracy when evaluating a diamond is GIA (Gemological Institute of America).
